InGame Suggestion 01: By Class Top Notcher and 3v3

i know this suggestion sounds awkward, but.. is it possible to have this kind of PvP? by class?
and most of the players here know 3v3 or 2v2 pvp from other servers, but how bout in FlameRO? wouldnt that be good?
but, mind that in 3v3, only one job type/class per group..
